Previous results indicate that SnO2 films, when suitably activated, make highly interesting, low-voltage electron emission for voltages approximately or 2 volts sources of electrons, i.e., cold-cathodes. However, relatively little basic research has been done on SnO2 and even less is known about its surface or the mechanism for cold-cathode emission. The authors have undertaken a preliminary study to investigate SnO2 and the processes which occur during activation using Ultraviolet Photoemission Spectroscopy UPS as their primary tool. Preliminary studies of O2 and H2 chemisorption on the closely related oxide, ZnO, have also been performed.
